No, that just seems to be variable speed power assisted steering - so at high speeds it gives you little assistance, at low speeds it gives you loads.

With this it literally changes how much your wheel turns for the same amount of steering wheel/yoke movement. So at high speeds turning the yoke by 90 degrees will turn the wheels maybe 10 degrees so you don't kill yourself, but at low speeds the exact same movement will move the wheels 45 degrees so the car is a lot more manoeuvrable.
